A race of aliens have evolved themselves to the point that they've eliminated their physical beings and exist only as beams of light. However, somewhere along the way they left behind the pleasures of the flesh, so they send an emissary named Kara to Earth to experience as many sensual delights as possible that can be recorded for all of the species to access. Since Kara has been designed to represent a perfect specimen of human female, she has little trouble finding Earth men willing to help her -- all in the name of science, of course.
